Hi-Check non-return valveThis high integ rity full bore no n-return va lve elimina testhe risk of b ac k flow out of the proc ess stream. Thedesign utilises a spring loaded poppet to ensure leakproof p erformanc e. The Hi-Chec k Non Return Va lve isdesigned for higher flow and low pressure drop acrossthe valve - having a larger through bore than mostother manufac turers eq uivalent prod uct.As s tand a rd a viton se a l will be s upplied with a crac kpressure of 10 psig. A wide variety of seat materialsand crack pressures are available on request.In the event of the required valve configuration notbeing shown please do not hesitate to contact thefac tory as P a rker Hannifin IP D offer bes poke custo merso lutions.

Pro-Bloc for injection applications -part numberingIn order to specify the addition of an injection probea nd non-return valve to your P ro-Bloc s imply ad d a J to the beg inning of the part numbe r i.e. J P B o rFEJ P B The probe length in mm must be ad ded tothe end of the part number, see below. Due to theinternal bore size of standard ASME flanges probesca n only be installed o n a rang e of flange s - pleas e s eethe table in the sampling Pro-Bloc section (previouspage).The probe length must b e s pec ified from the raisedfac e to the end o f the prob e in mm, to the nearest mm.Probes are supplied to suit the insertion lengthreq uired by the pipeline a nd thus mus t be s pec ified b ythe c ustomer.A wide va riety of end prepa ra tions a nd s upport colla rs

Pro-Bloc for injection applications (10mm + 15mm bore only)This ma nifold rang e is de signe d to replac e co nventiona l multiple-va lve insta lla tions w here injec tion into theproc es s s trea m is req uired. This d esign ha s b een d eveloped to inject d irectly into the proces s s trea m a t fullsystem pressure. All of the options and configurations shown within the standard Pro-Bloc range can be offeredfor injection se rvice by the a dd ition o f a cus tomise d injection probe w hich e xtends from the pipe flange into theprocess stream. Pro-Blocs for injection applications include an injection probe which enables the fluid to beinjected directly into the process stream and a high integrity full bore non-return valve to eliminate the risk of backflow out of the proces s stream.
